In this work we have bridged between the SMEFT and HEFT formalisms following the work of two other groups [1]}, [2]}, [3]}, [4]}, [5]}.
We have focused on the Higgs-flare function \(\mathcal {F}\)  that controls the derivative couplings of two Goldstone bosons \(\omega _i\)  to any number of Higgs bosons.
We have exhaustively studied this flare function \(\mathcal {F}\)  and particularly addressed the existence of its key zero at a symmetric point in the \((\omega _i,h)\)  field space.
